With labor day marking the traditional end of summer in the states, many public pools hose a "doggie dive in" before emptying the pool for the season. I attended one with my pooch, and witnessed a young lady in a bikini go in with her dog (40ish pound dog). The dog wasn't happy, resulting in a mild wardrobe malfunction, no big deal.

But what if it was worse? Dog spazzes out and rips the top in half. Now she is in 4ftt of water with a broken bikini and covered only by a squirming dog. Can't really get out without releasing the dog and exposing herself. Can't really stay in with her dog trying to get out. The shallow end was packed with kids when I went, so that option is probably out.
